Trying to build an entire elite spec on top of a weak core class it's like trying to build a castle ...in the middle of a swamp; without a strong foundation you cannot hope to build something that will last the "testament of time" .
It's 2020, we are the doorstep of a 3rd expansion...and we still have professions with very weakened core concept, that lack identity and purpose...no utility in any spectrum of the game, what kind of balance is that? If I have to make a comparison.....
S ) Guardian and Necro - they both serve a purpose, have strong trait choices
A ) Ranger, Revenant , Thief - they are very viable and fun to play
B ) Warrior and Mesmer - somehow usable and offer a reliable foundation for future elites, easy to fix with numbers
C ) Elementalist and Engineer - Terrible in all aspects , outdated weapon skills and utilities , that little good they have get constantly dumped on to reign in powerful elites created as compensation for the abysmal state of the core counterpart
B ) and C ) need immediate attention , we need skill reworks here urgently....and honestly I don't know how you're trying to create a 3rd elite while ignoring the sorry state of some core professions
